init，就会生成这三个文件，我们只需要将它们拷贝过来使用即可。总结:<code>_config.yml</code>，<code>theme/</code>，<code>source/</code>，<code>scaffolds/</code>，<code>package.json</code>，<code>.gitignore</code>，是需要拷贝的。</li><li>再讨论下哪些文件是不必拷贝的，或者说可以删除的：首先是<code>.git文件</code>，无论是在站点根目录下，还是主题目录下的.git文件，都可以删掉。然后是文件夹<code>node_modules</code>（在用npm install会重新生成），<code>public</code>（这个在用hexo g时会重新生成），<code>.deploy_git文件夹</code>（在使用hexo d时也会重新生成），<code>db.json文件</code>。其实上面这些文件也就是是.gitignore文件里面记载的可以忽略的内容。总结：<code>.git/</code>，<code>node_modules/</code>，<code>public/</code>，<code>.deploy_git/</code>，<code>db.json文件</code>需要删除。</li></ol><h3 id="模块安装"><a href="#模块安装" class="headerlink"></a>模块安装</h3><p>在新拷贝的文件夹里，右键选择<code>git bash</code>，使用 <code>npm install</code> 命令，进行模块安装。这里不要使用hexo init初始化，因为有的文件我们已经拷贝生成过来了，所以不必用hexo init去整体初始化，如果不慎在此时用了hexo      init，则站点的配置文件_config.yml里面内容会被清空使用默认值，所以这一步一定要慎重，不要用hexo init。</p><h3 id="安装一些必要组件"><a href="#安装一些必要组件"
